The Model 844 4-Port Intersite Link provides enhanced linking capacity to a Zetron Model 827- based MPT 1327 trunked radio system. It provides four 4-wire audio ports and four RS-232 serial data ports. The 4-wire audio and data ports provide a gateway for linking conversation audio and call setup data essential for roaming trunked network operation. Multisite operation allows mobile units to roam throughout the network without losing any system functionality. Roaming units are located and can receive calls from a telephone or another radio unit. In addition, multisite operation allows a group call to include up to six sites.
